In the same kind of thing the OP is asking for, if only there was something to teach people how to drive their car properly irl... Something that could be called a "driving licence". With that, i would never be worried to cross the road of misbehaving drivers again ! Because there is absolutly no way that countless people, once they are done with their lessons, tests and tutorials, will start to forget them, or even worse : ignore them, to do what they want instead.

Irony aside, if underperforming players are making you so sick, then you are probably better off opening a "high dps, wall to wall pulls, no zero dps healer" group in PF.
